NAME

       ltsp-update-image - generate an NBD image from an LTSP chroot

SYNOPSIS

       ltsp-update-image [OPTION] [CHROOT...]

DESCRIPTION

       Generates  a  compressed  squashfs  NBD  image  from an LTSP chroot and
       exports it with nbd-server. Chroot can be a full path or a subdirectory
       of the LTSP base directory, and it defaults to the host architecture if
       unset.

OPTIONS

       -b, --base[=PATH]
              The LTSP base directory Defaults to /opt/ltsp if unspecified.

       -c, --cleanup
              Temporarily remove user accounts,  logs,  caches  etc  from  the
              chroot  before  exporting the image. The chroot arch is required
              to be compatible with the server arch.

       -e, --exclude[=LIST]
              List of dirs/files to  exclude  from  the  image.   This  is  in
              addition to /etc/ltsp/ltsp-update-image.excludes.

       -f, --config-nbd
              Generate   appropriate  nbd-server  configuration  files.   It's
              automatically set if NFS isn't used or if other  LTSP  generated
              nbd-server configuration files already exist.

       -h, --help
              Displays the ltsp-update-image help message.

       -m, --no-compress
              Don't compress the generated image.

       -n, --no-backup
              Don't backup chroot.img to chroot.img.old.

       -r, --revert
              Swap chroot.img with chroot.img.old and update kernels.

       --version
              Output version information and exit.

AVAILABILITY

       Part  of  the  ltsp  package  and  the latest versions are available in
       source form from https://launchpad.net/products/ltsp.

FILES

       /etc/ltsp/<tool>.conf:  Upon   execution   the   tool   will   read   a
       configuration file to override built-in defaults.

       Values  are  NAME="VALUE"  pairs,  with # representing commented lines.
       most commandline options have an equivalent. an  example  Debian  based
       system with an alternate base location, architecture, and distribution:

        # set alternate default location for ltsp chroot (--base)
        BASE="/srv/ltsp"
        # build an amd64 chroot by default (--arch)
        ARCH="amd64"
        # build a Debian sid environment (--dist)
        DIST="sid"

       /etc/ltsp/ltsp-server.conf:  Each  LTSP server tool will read a generic
       configuration file. This file  is  typically  used  for  setting  BASE,
       TFTP_DIRS  and  TFTP_BOOT_DIR.  These settings are overwritten by those
       set in specific tool configs.
